[PATCH] drm/amdgpu/display: make various arrays static, makes object smaller
From: Colin King
Date: Mon Oct 07 2019 - 17:59:03 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Don't populate the arrays on the stack but instead make them
static. Makes the object code smaller by 158 bytes.
Before:
text data bss dec hex filename
32468 2072 0 34540 86ec display/dc/bios/bios_parser.o
22198 1088 0 23286 5af6 display/dc/bios/bios_parser2.o
22278 1076 0 23354 5b3a display/dc/dce/dce_mem_input.o
81180
After:
text data bss dec hex filename
32341 2136 0 34477 86ad display/dc/bios/bios_parser.o
22070 1184 0 23254 5ad6 display/dc/bios/bios_parser2.o
22119 1172 0 23291 5afb display/dc/dce/dce_mem_input.o
(gcc version 9.2.1, amd64)
